I’ve gotta be honest, I thought I’d be sadder when Echo left the team to join Rex, but you could see he was just so despondent whenever he was on a mission, especially one which could be more “frivolous” that I’m happy he gets to go and do what he considers fulfilling.
It also doesn’t help that it feels like he never really got a voice in the team, never got to use his skills to help during a battle (anything he does can usually be done better by Tech and/or Hunter), and it overall felt like the showrunners were just waiting to write him out for this entire season and a half, barring the first two episodes of s2. I’m unsure if most viewers (or even the batch!) will miss him after he’s gone.
However, the goodbye scene with Omega felt very real and emotional—because she’s never known the crew without Echo, and has apparently been doing lessons with him and overall I was almost a blubbering mess during that one.
Honestly, as a fan of Echo and Omega, I’m kind of nonplussed that their growing relationship was only told during that scene instead of shown during any of the episodes in season 2, but ah well.
